Solution Overview

Problem

Users face challenges in finding connected speakers that meet their specific needs in terms of features and cost, as existing products often require multiple variants to accommodate different user preferences, leading to increased manufacturing costs and limited flexibility.

Innovation Solution

A modular audio reproduction equipment design that includes a main module capable of operating independently or with additional modules, such as a microphone module with a battery for portable use, allowing users to customize their speaker configuration based on their needs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a connected speaker includes a microphone array for voice recognition, then voice recognition functionality is improved, but cost increases and may deter users who do not need this feature

Engineering Contradiction:
Improvevoice recognition functionalityVSAvoidmanufacturing cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The speaker system is divided into separate modules: a main speaker unit and an optional microphone array module. Users can choose to purchase only the main speaker without the microphone array, or add the microphone module separately. This segmentation allows the base product to be manufactured at lower cost while offering optional functionality for users who need voice recognition.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The main speaker unit is designed with universal functionality that serves both users who want simple audio playback and users who need voice recognition. The universal base module includes audio reproduction components, communication components, and power supply, which can operate independently or in combination with the optional microphone array module.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Measurement precision

If the microphone array is positioned on an upper part of the speaker, then sound signal capture is optimized for low-positioned speakers, but the design becomes fixed and cannot accommodate high-positioned speakers

Engineering Contradiction:
Improvesound signal captureVSAvoidposition adaptability
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The microphone array is separated from the main speaker unit and placed in its own detachable module. This allows the microphone array to be positioned at different heights relative to the main speaker depending on the user's needs. The modular design enables the microphone module to be attached at various positions or orientations to optimize sound capture for different placement scenarios (low or high position).

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system transitions from a fixed microphone array position to a dynamic, adjustable configuration. The detachable microphone module can be attached in different orientations and positions, allowing the system to adapt its microphone array position dynamically based on whether the speaker is placed low or high, thereby optimizing sound capture for each scenario.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If the speaker includes a battery for portable use, then portability is improved, but cost increases for users who prefer stationary mains-powered use

Engineering Contradiction:
Improveportable use capabilityVSAvoidmanufacturing cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The battery power supply is segmented as an optional module that can be added to or removed from the main speaker unit. Users who need portable use can purchase the speaker with the battery module integrated, while users who prefer stationary use can purchase the same base speaker without the battery module, reducing manufacturing costs for both variants.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The main speaker unit is designed with universal power supply capability that can accept either mains power or battery power. The power supply components are configured to work with both power sources, allowing the same base device to serve both stationary and portable use cases depending on which power module is attached or integrated.

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Adaptability or versatility

If the manufacturer markets many different products with distinct functionalities, then user needs are satisfied, but manufacturing complexity and cost increase due to separate production lines

Engineering Contradiction:
Improveproduct functionality varietyVSAvoidproduction line complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The product line is segmented into standardized modules (main speaker unit, microphone array module, battery module) that can be independently manufactured and then assembled in different combinations. This allows the manufacturer to produce each module on separate specialized production lines while still offering a variety of final product configurations, reducing overall manufacturing complexity compared to producing entirely different products from scratch.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The manufacturer creates a universal base speaker module that serves as the foundation for multiple product variants. This universal module can be combined with different optional modules (microphone array, battery, or both) to create different product configurations, allowing a single production line to produce the base unit that can then be assembled into various functional variants, reducing the need for entirely separate production lines.

Inventive Principle:
Principle #6Universality (Multi-functionality)
